DP's always implemented a really smart tactic on the Nadal serve, and that is to stand miles back. Gives Nadal virtually no cheap points and he doesn't mind necessarily hitting from far back due to his length and power. I first noticed it when they played at Miami in 2009.
And yes Kate, Rafa definitely going for the DTL forehand a lot more. It bothers me that throughout his career he's often tended to wait till he's behind in these matches to go for it, but better late than never
Haha, but this further highlights the point, if you're playing Nadal, you'll take your chances with him acing you. If he does it, too good. He won't do it often.
